Error Msg: E1512 - Empty Prototype... Beginner on T7 Tutorial

Hello,

We (my son and I) are going through the T7 tutorial: Outdoor Level Template.

We clicked New Level, Project Wizard
Selected Outdoor Level
We filled in the Project Path and Folder the same as in the Tutorial (except using the correct folder name)

Level opened as in tutorial.
We checked the Project Path and Folder.
The Folder was there, along with its subFolders (Code, etc.)

We Clicked Run then OK

Then we get the error message:

E1512 - Empty Prototype Called in Main

Please Help us before we give up on GameStudio.

Thanks,


MikeT

If you give up that fast, you should ask yourself if game design is the right thing for you.
Why do you use such an old gamestudio version anyway, 7.36? Where did you get it?
You should update your A7 version, this will fix many issues you may encounter.

Hi SuperKu,
Thanks for your fast response.

The Version (as displayed in WED) is really:
Gamestudio Free 7.84 /WED V6.944
It was downloaded 6/2/2010

The 7.36 came from the Help > About on the initial window that opens when the program starts (SED):
SED Version 7.36.0

As mentioned I'm just a beginner.

We are not ready to give up on Game Programming.
However, we are searching for a suitable game developement platform. Any program that gives error message(s) on the initial use gives cause for concern.

If the error can be resolved, with the forum's help, that will indicate two important things:
1. That the program is basically sound.
2. The Forum is responsive.

I am heartened to have received a quick response. Thanks!

BTW: The Computer and OS info is:
Toshiba Laptop: Satellite L305D
CPU: AMD Sempron SI-42 2.1GHz
3.00 GB Ram
Windows 7 Home Premium
ATI Radeon 3100 Graphics

Thanks in advance for you help.

to 99% you have forgotten a ';' somewhere. (without the ')

Hi Asgadir,

Currently, we are only at end of the 30 second guide:
http://www.opserver.de/wiki/index.php/30_Second_Guide

Since this only involves the Project Wizard, we haven't been doing any coding yet.

Could it be that the Project Wizard is leaving out the ';' ?

BTW: murlok on 5/26/2010 posted a similar question - with 0 relies:

Did you change something in the script? "Empty Prototype" happens when you define a function prototpye like this:

And then call it without writing the actual function.

That is a bit strange. I just gave it a try and everything works fine.
When does that error appear?
I thought that the code might be outdated, but that doesn´t seem to be the case (and actually nearly never should, as gamestudio should usually be completely backwards compatible). The only thing I could think of is, that there is some file missing for you, which exists on my system due to updating. But that should give you another error message then.

Post your acklog.txt here. To generate it, add the -diag command.

I've just tried it and it works fine for me, too, although the outdoor example looks and feels horrible, don't expect much.
Make sure to check the following list:

Hi Superku,

I checked and everything in your list is there.

Maybe the acklog.txt will help.

I haven't touched any of the coding generated by the Project Wizard.

Slin: As to when the error occurs:
The Wizard generates the level with terrain and entities fine.

1. I click the run (traffic light) button.
2. A dialog pops us with Engine Options: "myproj.c -nx 30", click ok
3. The information window appear with 'Compiling MYPROJ.C' then '2 objects'. Then the Error E1512 comes up.

I've also tried the build button along with the various build options. No error when building.
The error still occurs only with the run button.

In WED, I also tried the Resourses tab, Script files, MyProj.c > Open.
In SED, trying the Run Current Script, the Test Run or the Debug Run buttons all generated the error.


Thanks to everyone for your help,



MikeT

There is nothing wrong with your (generated) code, the problem is here:



Then there is the following code in your main-function (myProj.c):



Because project_load and project_update are not found, the engine outputs the "Empty prototype called in main" error. I don't use dll functions myself but this sounds as the t7.dll could not be loaded. When you run your script/ project, the white start window lists which dlls have been loaded, f.i.:
acknet.dll opened
ackwii.dll opened
t7.dll opened.
Check if the bold line appears in your start window.

The white start window:
Mouse Found
Speakers (Realtek...)
ATI Radeon 3100...
Compiling MYPROJ.C - [Esc] to abort.............0.270 sec.
2 objects

Then the E1512 error pops up.

There is no mention of dll's that load.

http://drop.io/04oko54/asset/gstudio-error-jpg

Are there the following Dlls in the
XX:/Program Files/GStdio7/acknex_plugins/ folder?

-t7.dll
-ackport.dll
-ackwii.dll


Do you have VC++ redistributable correctly installed?

The free version does not support DLLs (EDIT: as engine plug-ins), thus the Project Wizard won't work unless you have the Extra, Com or Pro edition (the templates are being replaced anyway).

You can download the 30-days trial, then you will be able to use the Project Wizard.

EDIT: I could be wrong.

Wow, that I didn't know yet, sorry.

I'm glad to find out what the problem was.

Perhaps a notice might be in order for the tutorial.
(Extra, Com or Pro editions only)


Thanks for everybody's replies.

We will go ahead and try some other tutorials.


MikeT

Thx Superku!

After spending several hours attempting to get the A7 templates to work, and another hour in the forums, your post explained to me my problem. You saved me hours of additional frustration.

(NOTE TO ACKNET) It does seem to me that if the free version does not support the .dll files, perhaps the free version shouldn't provide a wizard that forces them to be used
